TEMPERATURE ALARM DEVICE.

Temperature Alarm Devices, of which the j following is a full, clear, and exact specification.

My invention relates to temperature alarm devices and refers particularly to thermometer control devices.

One object of my invention'is a device whereby an alarm will be sounded by an increase of temperature above a predetermined point. A

Another object of my invention is a device whereby an, alarm will be sounded continu'- ously until manually interrupted.

My device has numerous applications amongwhioh I specifically mentionits use as a fire alarm and as a means of notification when the temperature within a chimney,'or flue exceeds a predetermined temperature.

My device depends for its operativeness upon the increase of temperature as registered by a mercury, or other liquid, thermometer. r 1

The-objects and advantages of my device will be evident upon a consideration of my drawings, specification and claims.

In the particular form of the device of my inventiomshown' in the accompanying drawings, similar parts are designatedby similar numerals.

. Figure 1 is a side elevation, partly in section and partly broken away for clearness of disclosure. 7

Figure 2 is a section through the line 22 of Figure'l.

Figure 3 is a broken enlarged elevation of a portion of the make and brake device showing the device in a completed circuit position. w

The particular form of the device of my invention, shown in the accompanying drawings, comprises a box having the back 10, the annular side 11 and the front annular member 12. The foraminous side 11 has a series of openings 13, 13. The front 12 carries a plate of glass 14, and is hinged to the side 11 at 15. A hinged member 16 is fixedly attached to the side 11 and the opening 17 is capable of placement over the ring staple Specification of Letters Patent. -Pa,tenfedi M 1 21. 1922 Application filedFebruary 8, I921.

18, carried by the extension 19 of the front 12,-thus allowing'the insertion of a pad lock 20- whereby the front maybe locked in a closed position. A supporting member 21 extends transversely across the box and is fixedly attached to the side 11. The back has an inwardly extended portion 22. The two threaded pointedmembers 23 and 24 are threaded withinope'nings in the members2l and 22 respectively and are in absolute'ahgnment with each other.

7 The member s 23 and 24 carry the lock units25 and 26 respectively. I

A revoluble device comprises the annular member 27 carrying the'two plugs 28,

'29, each of which has a conical recess into which the pointed ends of the members 23 and 24 may be inserted to act as revoluble points for the member 27.

f A threaded belt 30 is screwed into the rod 35. A ball 36 is movable within the tube 33,-and a" nut 37 is threaded upon the member 35.

A similar tube 31, containing a similar tube and ball, a similar, ball 32 with threaded member 35 and nut 37 are similarly attached to the member 27.

Screwed into the member 27 is a thermometer holder 38, carrying the thermometer 39, the lower portion of the holder eshavmg the threaded member 40 carrying the nut.41.

The tubes 31* and 31 andthe thermometer holder'38 are preferably placed equidistant from each other upon the member 27.

Fixedly attached to the side 11', and sepa rated therefrom, by the insulating material 52, is an electric conductable supporting member 42. The member 42 carries the electric con'd'uctable member 43 and is separated therefrom by the insulating material The member 43 carries the two free swingbattery and the electrically actuated bell 5:1. it is evident, therefore, that if the member 46, or the member 46', be brought into contact with the member 42, the electric circuit will be completed and the alarm bell sounded.

The mode of the application and method of use of my illustrated device is as followsf The device, as shown, particularly in Figure 3., is in-a position where one of the axial lines A, A, A is in an absolutely vertical position. The front glass door is opened and the device moved into the position shown by the axial lines B, B, B in which the previously vertical line has been moved onto-l its vertical position. The device is then balanced accurately in this position, which is accomplished by varying; the position of the balls 32 and 32, the more delicate balancing being accomplished by means of the nuts 37, 37 and 4-1. hen the device is in accurate balance, the door is closed and locked. The temperature of the surrounding air is transmitted through the openings l3, l3, 13 oi the device and affects the mercury in the thermometer 39. A raise in temperature will cause the mercury to rise in the thermometer destroying the equilibrium and causing the device to rotate upon its pivotal point in the direction of the arrow in l igure 1, the rotation being facilitated by the ball within the tube 31 rolling toward the ball 32. The rotation of the device will bring the tube 3i against the member 4-6, causing it to abut upon the member 42, as shown in Figure thus com-- pletingthe electric circuit and sounding the bell alarm 51, which position will be maintained until the device'is manually revolved to release the member 4-6 from its abutment upon the member l reverse rotation of the device" @an be obtained by balancing the device upon axial lines upon the opposite side or the viu-tical axial line A, in which case the circuit will be completed by the abutment oil? the tube 81 upon the member 46 and of the latter upon the member 4-2.

It will thus be seen that the device of my invention discloses means whereby a raise of temperature will. react through the medium of a thermometer to sound an alarm.

I do not limit myself to the iarticular size, shape, number or arrangement oi parts shown and described, alloi which may be varied without going beyond the scope oi my invention as shown, described and cl aimed.

What I claim is:

1 In a device oi? the character specified, in combination, a casing, a pivotal member within the using, a plurality of arms carried by the pivotal member, means for balancing the arms in a non-vertical position, a thermometer carried by one of the arms and means whereby an increase in temperature will cause the liquid within the thermometer to revolve the arms completing an electric circuit and soundin an alarm.

In a device of the character specified, in combination, a casing, a pivotal member within the cars a plurality of arms carried by the pivotal member, a removable weight carried by each arm, a thermometer (arr d by one of the arms and means whereby an increase in tempe 'ature will cause the liquid within the thermometer to revolve the anus completing an electric circuit and sounding an alarm.

o. In a device of the character specified,

in combination, a casing, a pivotal member within the casing, a pltn'ality of tubes carried by the pivotal member, means for balancing the tubes in non-vertical position, a thermometer within one of the tubes, means .vhereby the rise of the liquid will revolve the tubes completing an electric circuit and sounding an alarm.
